Methods: Study 1 analyzed the effects of a RCT analyzing the impact of a multiple lifestyle computer tailored feedback system in order to stimulate adults to adopt a healthy lifestyle consisting of non-smoking, sufficient physical activity and the consumption of sufficient fruits and vegetables, and the reduction of fact consumption. The tailored intervention group received three print tailored letters and the generic information group received three print generic letters. Study 2 analyzed whether it is likely to change smoking behaviour within a multiple life style approach using Latent Class Cluster Analysis.

Results: Study 1 found significant treatment effects were after one year on the reduction of fat, fruit and vegetables consumption, and for increased physical activity. No significant effects were found for smoking. Study 2 showed that alcohol and smoking should be regarded as a separate health cluster.

Conclusions: A multiple life style approach may need to consider the fact that different clusters of health behaviors may exist, and that the readiness for change within the population may differ from cluster to cluster. This requires a step-wise tailored approach instead of a simple tailored approach.
